Hi Ali, When you put nodes underneath a ClipNode those nodes should inherit the required GL_CLIP_PLANEi, so in theory it should work right, however, as I've never mixed osgText with clipping I can only say I don't see a reason in principle when it wouldn't work. If you put the subgraphs you want to clip in a different subgraph you'll need to set the GL_CLIP_PLANEi.
